To (t/Z when?, zit may coli/cern:

Beit known that l, VVILLTAM E. RUNDLE, a citizen of the United States,and a resident of East Orange, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements inUndergrouiid-Cable- System Charts, of which the following is aspecification.

This invention relates to an undergroundcable-system chart;` and itsprincipal object is to provide a chart of an underground-cable systemcontaining all the principal points of inforn'iation necessary to aproper understanding of the organization of such a system.

Heretofore it has been customary to keep the necessary information orrecords relating to underground-cable systems in such a manner that buta small portion of the systein--frequently only a single manhole,withits connections, dimensions, Sac- Would be shown on a sheet, and inusing such recordsit is necessary to examine a large number ofsuccessive sheets in order to obtain even a :fair idea of the positionsand connections of the multitude of elements comprised in the system. lnmy improved chart, however, the complete layout of an entire system isshown, and on this chart, either by symbols or other suitableprovisions, all of the principal items of information with respect tothe positions, connections, dsc. of the elements of an underground-cablesystem are given in such a manner that the plan of the system as a wholeis clearly presented and is easily understood without the labor andfatigue which result from the selection of various items from a largemass of data and the mental assemblage of these items. In this chartsome of the principal provisions or symbols employed are thoseindicating the points at which a cable is drawn into the manholes of thesystem, the joints made at such manholes, and the particular duct whichreceives the cable when the conduit is a multiple-d uct one, asisusually the case. Other important provisions are those indicating'whether a duct contains one or more cables, whether the cable is laid oris on hand but not laid, whether the cable, though not on hand, has beenordered, which cable-sections are drawn from the same reels as the cableof the next preceding sections, respectively, &c.

ln the drawings accompanying this specilication and forming part of thepresent application, Figure l is a chart or diagram of anunderground-cable system illustratingl graphically the principalelements of such a system and the manner in which those elements areconnected and organized. Fig. 2 is a map of the streets or highwayscontaining the underground cable, and Figs. 3 to 19, inclusive, areenlarged details illustrating the various provisions or symbolsindicating the different elements and conditions found in the system.

Similar characters designate like parts in all the figures of thedrawings.

rlhe chart shown in Fig. 1 illustrates one specilic assemblage ofsymbols, Sac., indicating how the elements of one particular system arecombined at one stage in the progress of the work thereon, and itrepresents substantially all of the leading elements and conditionsfound in an undergrouncl-cable system. In this figure each cable of agiven cross-section is preferably shown as separated from the othercables of the system in order to avoid the confusion which would resultfrom the use of different graphical provisions or symbols forindicating' cables of different sizes. In this chart eighteen diiierentcables are shown, most of which are passed singly through the ducts ofsuitable conduits,usually of the multiple-duct type, while in a fewcases these cables are shown assembled in pairs to indicate that twocables are passed through a single duet, suitable provisions or symbolsbeing used to distinguish between a duct having but one cable thereinand a duct containing' two cables. rlhe provisions which I prefer toemploy for indicating the cable graphically are a pair of parallel linesof considerable length. Different provisions may be used to indicatediiierent conditions with respect to the cable, and in this case heavyand lightfull lines, either in pairs or in groups of three andcorresponding dotted light lines, are used to indicate whether the cableis laid or unlaid, though on hand, orwhether it is merely orderedV andalso whether aduct contains one ortwo cables. ln

Figs. 3vto 7, inclusive, the symbols indicating these various conditionsof the cable are illustrated in detail. As all of these cables havetheir beginning at the power-house, the different symbols both in thechart and in the detail views are shown in most cases as reading fromthe power-house, which is indicated by the line 2, from which line thesymbols shown in Figs. 3 to 10, inclusive, are drawn.

In Fig'. 3 two light dotted parallel lines indicate a single cable andalso show that the cable has been ordered, but not received. Three lightdotted parallel lines, as shown in Fig. 4, indicate the same conditionsand also show that there-are two cables in a single duct instead of one.The two light f'ull parallel lines in Fig'. 5 indicate that the cable ison hand, but not laid, while two heavy full parallel lines, as shown inFig. 6, indicate that the cable is laid. Three heavy full parallellines, as indicated in Fig. 7, denote two cables drawn into a singleduct. These various provisions or symbols are designated` respectively,by 3, 4, 5, 6, and 7, and it will be clear from these symbols thatwherever but two parallel lines are shown, whether they be heavy, light,or dotted lines, a single cable is indicated, while when three parallellines are shown two cables in a single duct are indicated regardless of'the particular character of' the lines shown, the differences in thecharacteristics of' the lines themselves indicating' different,conditions with respect to the cable regardless of whether one or twocables are shown.

ln Fig. 1 three light parallel lines (indicated by 5') denote two cableswhich are on hand, but not laid, and are to be drawn into a single duct.l

1n underground-cable work each cable usually intersects or is drawn intoa large number of manholes, and an important element o f` my chart isthe employment of' suitable provisions or symbols for indicatingmanholes and associated elements. Any suitable symbolusuch, for example,as the square 8-may indicate a manhole into which a cable is drawn, andthe number of manholes through which a cable passes is illustratedseparately for each separate single cable or pair of cables. All thesemanholes may have individual distinv guishing marks or numbers-as, forexample,

the Vnumbers 504 to 507, inclusive, 600 to 605,

508 to 514, 100 to 104, 200 to 204, and 800 to S10-these differentseries being numbered differently because each series is located on adifferent street or highway from all the others. The continuations of'the different series are indicated in several instances without specialdistinguishing numbers.

Associated with each manhole may be another symbol or symbols forindicating other elements ofl the system. The principal symbol of thischaracter is that shown at 9, which represents the joint at amanholethat is to say, the connection of cable ends in a precedingsection.

.senting duets of equal size.

manhole. Another provision shown is a pair of' short parallel lines 10,which symbol indicates that the cable in its Asection is taken from thesame reel as that used in the next For the purpose of' identif'ying thereels from which the dilferent sections of the cable are drawnprovisions -such as identifying marks or figures may be used. Thesenumbers are placed on the respective sections ofl the cable at thebeginning of each section, as shown at 9800, 9801, 9802, 9803, 9804,Sac.

Other provisions may also be used to indicate the time when and theperson by Whom each particular portion of' the work is completed,numbers being used to indicate the month and day of' the month and thelast two figures of' a year to indicate a year, ywhile a letterforexample, K, D, or M-indicates the foreman or other person who makes ajoint, superintends drawing in of the cable, &c. The length of cablebetween manholes may, if desired, be indicated by placing on eachsection of` cable a number representing the exact length of such portionof' cable, as indicated, for example, at 382, 167', 315', and 345.

One of the most important provisions, however, that I have employed inthis chart is the means Jfor indicating the type of multipleduct conduitinto which each cable is drawn and the particular duct in which suchcable is located. In Figs. 13 to 19, inclusive, I have shown graphicallyseven different provisions indicating seven different species ofconduits of' the same general type#that is to say, conduits having ductsof' like cross-section. The full-size conduit indicated in Fig. 13 hastwenty-fivecable-ducts disposed in live rows of live ducts each, whilethe conduits indicated in the other views are of similar constructionand have fewer ducts. All of these provisions or symbols, however,

'have one characteristic in common-that is to say, they are allgeometrical figures divisible by cross-section lines 12 into spacesrepre- The different symbols indicating the different species of ofmultiple duct conduits are represented, respectively, by 11 11a 11b 11C11d 11e 11i'. Each ofl these symbols is placed adjacent to acorresponding portion of a cable and when so placed indicates that theconduit through which that portion of' the cable passes has the specificcross-section illustrated. In order to locate graphically the positionof each cable in the duct through which it passes, it is also necessaryto employ some means for distinguishinging the particular ductcontaining such cable, and this may be accomplished by using as a symbola dot located in the particular duct through which the cable is drawn.This is clearly illustrated in Figs. 13 to 19, inclusive. In Fig. 13,for instance, the dot 13 shows that the cable is drawn through the IOOleft-hand duct in the top row, it being' understood, as before stated,that each or' these symbols is read as looking away from the powerhousetowardthe end oi1 the line. This chart also illustrates the number ofcables running from the power-house and theiirst manhole at which thecables branch and also the number of cables running from this manhole507,

vit being' only necessary to count the number of dots in theduct-symbols of each group to determine the number of cables on eachline, most of the branches having three cables each.

Additional provisions may be used to indicate such other elements orfacts as may be or' importance, symbols, such as those shown at 15 and15 in Figs. 9 and 10, being used to in dicate, respectively, a terminalhaving the date or completion of the work displayed thereon and aterminal with no date thereon.

At the edge ot' the body of the chart, adjacent to the power-house,there will preferably be provisions,such as a tableor indicatingopposite each cable the characteristic mark or number of that cable andthe size or cross-section of the cable, these provisions being displayedin the columns designated, respectively, by 16 and 17.

While I have described my invention with relation to underground-cablesystems, l do not limit myself thereto, as the invention may be used forsystems of conductors placed overhead on cross-arms or in tunnels onracks, as will be readily understood.

What I claim is- 1. A chart for a system or' electrical conductors saidchart having thereon symbols running in one general direction forindicating a series of conductors which run in one general direction, incombination with symbols indicating local facts relating' to saidconductors the general direction or' corresponding' symbolsindicatinglocal facts relating to diiferent conductors being on a linetransverse to the general direction of said iirst symbols.
